White-Rodgers 1E30N-910 Thermostat

Precision-engineered for reliability in standard low-voltage systems, the White-Rodgers 1E30N-910 is a heavy-duty single stage mechanical thermostat designed specifically for heating-only applications. This 24V heat only thermostat features robust mercury free snap action contacts, ensuring accurate temperature regulation without the environmental hazards of older mercury-switch models. Built for the field, it serves as a universal mechanical thermostat replacement for hundreds of legacy White-Rodgers and competitive vertical-mount units performance-tested over decades. With an adjustable heat anticipator ranging from 0.15 to 1.2 Amps, technicians can fine-tune cycle rates to match the specific current draw of gas, oil, or electric furnaces. The integrated bimetal thermometer provides at-a-glance monitoring, while the enclosed contacts are protected by a dust cover to prevent fouling in residential or light commercial environments. Whether you are servicing a millivolt heating system or a standard 24VAC zone valve, this unit's R and W terminal configuration simplifies the retrofit process on two-wire or three-wire zone systems.

• Universal Retrofit Compatibility: Engineered as a direct drop-in replacement for hundreds of legacy White-Rodgers and competitor vertical models.
• Multi-Voltage Versatility: Fully compatible with both 24VAC systems and millivolt applications, including wall furnaces and floor heaters.
• Enhanced Reliability: Features enclosed snap-action contacts and a dust cover, making the unit resistant to vibration and debris interference.
• Precision Cycling: The adjustable heat anticipator allows for custom system matching to prevent overshooting or short-cycling of the heating plant.
• Easy Installation: Mounts directly to a standard junction box or wall surface with clear RH and W terminal designations for two-wire setups.

Is the White-Rodgers 1E30N-910 compatible with millivolt systems?
Yes, this model is designed to operate on both standard 24V AC control circuits and millivolt systems, making it ideal for gravity-fed gas furnaces and older floor heaters.

Can I use this thermostat to control an air conditioning unit?
No, this is a dedicated heating only thermostat designed for single-stage heat. It does not include cooling terminals (Y) or fan switching (G).

What wire terminals are available on this model?
The thermostat utilizes RH and W terminals. For three-wire zone valve applications, ensure your wiring diagram matches the snap-action contact requirements of this vertical-mount unit.

How do I adjust the system cycle rate?
The unit contains an internal adjustable heat anticipator. You can slide the contact arm to match the amp rating of your primary heating control to optimize performance.
